Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been found guilty of driving drunk of drugs or alcohol may qualify to get rehabilitation services because of their problem as opposed to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically will often be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it if it is an alternative. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than punishment. Much research has been completed to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that take part in rehabilitation have a better probability of remaining out of the system after treatment.
